Recently, the research team led by Pan Quan from the National Demonstrative College for Microelectronics, College of Engineering, Southern University of Science and Technology, has made a significant breakthrough in the field of high-speed communication and optoelectronic integrated circuit design. Their research achievements include: the first single-ended transceiver front-end chip operating at a rate of 224 Gb/s PAM-4; a 50 Gb/s PAM-4 receiver employing a current-reuse AFE and a single-loop half-rate referenceless CDR, significantly improving jitter tolerance and energy efficiency; and a CMOS monolithically integrated 28 Gb/s PAM-4 optical receiver for VCSEL optical link applications, achieving monolithic integration in CMOS technology.
